PROCESS FOR THE PRODUCTION OF SCULPTURES.

Application filed. May 21,

To all whom it may concern:

Be it known that I, VILHELM Hmsn, sculptor, a citizen of the German Republic, residing at Munich, Bavaria, Rheinbergerstr. 5, Germany, have invented new and useful Processes for the Production of Sculptures, of which the following is a specification.

This invention has for its object to provide an improved process for the production of sculptures by means of I photographic images.

The improved process according to this invention consists broadly in projecting by parallel beams of parallel light rays one or more photographic images of the desired dimensions on to the material to be sculptured, so that the desired sculpture can be produced directly in the said material.

The improved process will now be described more fully with reference to Figs. 1 and 2 of the accompanying drawings.

A plurality of photographic representations (preferably at least four), are taken, by means of the photographic camera, of the person whose sculpture is to be produced.

Fig. 1 illustrates the three main views a is the front elevation, Z) is the right hand side elevation, and c is the left hand side elevation of a photographic representation for the purposes of this invention.

These photographic representations are placed in projecting apparatus adaptedto efiect parallel projection of parallel beams of parallel light rays, and the several beams of parallel light rays such as shown in the IT. S. patent to Adams 1,163,192 patented Dec. 7 1915 with the objective removed, or as shown by the German patent to Steinheil 313,106 patented Sept. 13, 1922 (E B", 13, B in Fig. 2) are directed from opposite directions on to a common centre. The parallel light rays are so positioned that the beams of light rays B, B B, and B, are directed at exactly the same angles to one another as the relative angles at which the several photographic representations were taken.

If now a mass of plastic material is placed at the point A (Fig. 2), that is, the common point of intersection of the mutually intersecting light beams, the said plastic mass will receive the said beams, that is to say the 1924. Serial No. 714,922.

optical images of the photographic representations formed by said light beams. The sculptor is now enabled by observing these optical images. to produce the desired sculpture in the exact natural forms of the original, by simply following the details of the several intersecting photographic images appearinlg on the plastic mass.

By proceeding in the same manner as above described with reference to a portrait bust, any other body of the four sides of which photographic reproduction have been taken, can be converted into a sculpture in a short time with the use of very few means.

It is not absolutely necessary that the required views of the body to be sculptured shall be projected upon the plastic material all at one and the same time, by means of parallel beams of parallel light rays. The process may be performed by first executing all the contours and lines of one view in their exact longitudinal and lateral dimensions, but without reference to their depths. On now rotating the block of plastic ma terial on its own axis through one quarter of a revolution, and then projecting upon the said block the side view that is located at right angles to it, the forms that were indeterminate in respect of their depths, will now be intersected by the contours and lines now projected upon, and the said depths which were indeterminate up till now will now be clearly indicated.

Beliefs of greatly varying degrees of projection from their ground surfaces can also be produced quite easily by the process of the present invention, but in such cases only one photographic representation is needed, because the sculpture projects only to a small extent from the Iground surface.

What I claim is A process for the production of sculptures with the help of photographic images, which. consists in projecting the photographic images by means of parallel beams of parallel light rays on to the material to be sculptured, and then sculpturing said ma terial according to the intersecting lines of said photographic images.
